Q1. Which three statements regarding the BGP operations are correct? (Choose three) 

A. PE5 will set the local preferences 200 on all the prefixes sent to CE5 

B. PE5 will set the local preference to 200 on all the prefixes learned from CE5 

C. CE5 has received 5 prefixes from the PE5 EBGP peer 

D. CE5 has the BGP scan interval set to 30 seconds E. CE5 is announcing the 192.168.55.0/24 prefix via EBGP to the PE5 EBGP peer

Answer: C 

Q4. When a BGP route reflector receives an IBGP update from a non-client IBGP peer, the route 

A. To the other clients only 

B. To the EBGP peers only 

C. To the EBGP peers and other clients only 

D. To the EBGP peers and other clients and non-clients

Q5. A junior network engineer has just configured a new IBGP peering between two Cisco ASR9K PE routers in the network using the loopback interface of the router, but the IBGP neighborship is not able to be established. Which two verification steps will be helpful in troubleshooting this problem? (Choose two.) 

A. Verify that the network command under router BGP is configured correct on each router for announcing the router's loopback interface in BGP 

B. Verify that the ibgp-multihop command under the BGP neighbor is configured correctly on each router 

C. Verify that the loopback interfaces are reachable over the IGP 

D. Verify that the update-source loopback command under the BGP neighbor is configured correctly on each router 

E. Verify that the ttl-security command under the BGP neighbor is configured correctly on each router to enable the router to send the BGP packets using a proper TTL value 

F. Verify that the UDP port 179 traffic is not being blocked by an ACL or firewall between the two IBGP peers 

Answer: C,D 

Q6. Which four statements are correct regarding MSDP configurations and operations?  (Choose four.) 

A. The MSDP peers are also typically the RPs in respective routing domains. 

B. SA messages are flooded to all other MSDP peers without any restrictions 

C. On Cisco IOS, IOS-XE, and IOS-XR, the router can be configured to cache the SA messages to reduce the join latency 

D. SA messages are used to advertise active sources in a domain
